If you are unfamiliar with ladder logic and Omron addressing, have you checked the Omron website, they offer many e-learning classes which cover PLC basics and CX Programmer.

A little help to get you started: the nA and nD labels are just names that someone has given to a PLC memory address.  If you click on the contact or address in an instruction, you will see an address along with the name in a yellow bar near the bottom of your ladder.  The others (5.10, D540.00) are all memory addresses that you can find in the manuals above.
